We begin in the U.S., where thousands of protesters took to the streets across the country on Friday, angry over the fatal shootings of two U.S.

citizens by federal immigration agents.

From Houston to D.C.,

to Los Angeles, where riot police with shields lined up outside a detention center, facing off against demonstrators, some of whom came wearing gas masks in anticipation.

They were joined by students across the country who staged walkouts to show solidarity.

Here's Adi, who didn't give their last name.

In the meantime, the Justice Department has launched a civil rights investigation into the death of Alex Preti, the ICU nurse shot and killed by a federal immigration officer.

It could lead to criminal charges, though the legal bar is high.

There have been mixed messages from the Trump administration about whether they're in fact trying to dial down tensions.

In a post on Truth Social, President Trump on Friday described Preti as, quote, an agitator and perhaps an insurrectionist.

And while the protests continue, we're taking a deeper look at how all this unfolded.

On this weekend's episode of On Assignment, host Christopher Waljasper talks with Reuters reporters on the ground in Minneapolis covering the Trump administration's immigration crackdown and the tense moments after a second U.S.

citizen was killed by ICE agents.

We'll drop a link in the pod description.

Over to Iran now, where a series of explosions were heard in the southern port early Saturday.

The cause of the blast wasn't immediately clear when this podcast was published, and authorities haven't released any details.

It comes at a moment of rising tension between Tehran and Washington after Iranian authorities moved to quell the biggest protest the country has seen in three years.

And all of this is unfolding against the backdrop of continued Western concern over Iran's nuclear program.

Meanwhile, anger over the immigration crackdown has led to a partial government shutdown now in effect.
